Recently, ARTP products developed by TMAXTREE successfully passed all the testing requirements of UL certification, obtained the UL certificate of the United States, and obtained the pass to enter the North American market. This is another international safety certificate obtained by TMAXTREE based on the European CE certification in 2017, marking that the safety performance of TMAXTREE's ARTP products comes up to advanced world standard. UL certification in the United States is mainly aimed at product safety performance and protection performance. The certification test process is known for its strict and comprehensive, long evaluation cycle, and is one of the most authoritative safety certifications in the world. The atmospheric pressure room temperature plasma (ARTP) breeding instrument developed by TMAXTREE team adopts a new RF discharge technology, which uses inert gas discharge and can produce a large number of high-energy active particles at atmospheric room temperature; Studies have shown that active particles can be effectively used in the genetic material of cells and cause DNA structural damage, and then use the repair mechanism of cells with high fault tolerance to produce a large number of mutation sites, and finally obtain a large number of gene mutation libraries. The product has stronger mutation performance and richer mutation sites; Sequencing results showed that the mutation rate of this method was more than 1000 times higher than that of conventional methods; In addition, the product has the characteristics of mild discharge conditions, convenient and safe use, and can be widely used in the breeding of animals, plants and microorganisms.
